Gantt Chart

« Back to Glossary Index

Gantt Chart is the most popular and practical means of describing activities (tasks or events) demonstrated against time. A Gantt Chart assists project managers and team members in viewing the start dates, end dates, and milestones of project schedules in one simple stacked bar chart. The schedule of the projects is present on the left side of the Chart, and an appropriate timescale along the top. Every effort is shown by a bar; the position & length of the bar indicate the start & end date of the project.

A Gantt chart helps prepare and schedule projects of all sizes, although they help simplify complicated projects. Project management timelines & tasks are transformed into a horizontal bar chart, providing starting and ending dates, schedules & deadlines, including how much of the task is performed per stage & who the task owner is. Keeping tasks on the right track when the team size is large is beneficial.

Why Use Gantt Chart?

When the Company sets up a Gantt chart, he needs to think through all the tasks involved in the project. As a portion of this process, the product manager will determine who will be accountable for a specific task, how much time the specific task will need, and what difficulties his team may face. This distinct thinking assists him in ensuring that the schedule is functional, that the competent people are allocated to a specific task, and that the product manager has temporary solutions for potential problems before commencing.

They also support companies to run out practical project features, such as the least time required for delivery and which tasks need to be done before other tasks can begin. In addition, he can use them to recognize the crucial track, the arrangement of tasks that must be done separately to deliver the entire project on time. Finally, the product manager can use them to inform his sponsors of progress.
